Abstract
The ac magnetic susceptibility of the spin-glass S is found to have a power-law dependence on frequency near the freezing temperature. Extrapolating to zero frequency causes the peak in the real component to sharpen and shift to a lower temperature . That marks a phase transition is supported by exponents describing the divergence of the relaxation time, development below of the order parameter ), suppression of by a magnetic field, and scaling of the nonlinear susceptibility.
